11 CHECKFIRE Marine Electric SYSTEM APPLICATION AND DESCRIPTION 2016-JAN-30 REV. 02 PAGE 3 APPLICATION The CHECKFIRE Marine Electric Detection and Control System has been designed to be used in conjunction with an ANSUL fire suppression system requiring manual input as a means of actuation to meet the fire protection requirements of 46 CFR Subchapter T Small Passenger Vessels (Under 100 Gross Tons). Its unique low voltage low power operating system, designed to operate from a 12 or 24 VDC power input, makes the CHECKFIRE Marine detection system an ideal fire detection controller in applications where accessibility to standard 115 VAC power is either impractical or not available. The CHECKFIRE Marine system is primarily used for automatic fire detection in machinery spaces where an automatic fire detection system is required to accompany a manual fire suppression system; it may also be used for other shipboard hazard areas. Because of its rugged construction it is especially suited for protection of equipment that is subjected to extreme environmental and physical conditions. The CHECKFIRE Marine Electric is USCG approved under No /40/1. DESCRIPTION The complete CHECKFIRE Marine system is composed of components which are combined to provide automatic fire detection and control. Input Power The CHECKFIRE Marine control unit will accept an external 12 or 24 VDC regulated power source as its primary power. The control module uses an internal long life Lithium battery to provide a secondary supply in the event the external 12/24 VDC primary power source is interrupted. The internal battery has the capacity to perform all of the detection and control functions in the absence of primary power. Under quiescent load (system operating in a non-alarm condition), the secondary supply has the capacity to operate the system for a period of up to one year, and at the end of that period is capable of operating the system in a full alarm condition for 72 hours. Audible Alarms The control module provides an internal high pitch audible alarm that sounds whenever an alarm or trouble condition exists. Additionally, an alarm relay with a set of normally open/ normally closed (NO/NC) contacts is available for connection of an auxiliary high level alarm; and a trouble relay with a set of normally open contacts is available for remote trouble annunciation. Auxiliary Control Relay An auxiliary control relay with one set of 3 amp rated NO/ NC contacts is provided for auxiliary shutdown and control functions. This relay will transfer upon an alarm condition and is non-silenceable. Operator Interface Panel Operator interface is provided by a front panel mylar overlay containing four visual status LEDs, a silence switch and a reset switch. The status LEDs include: Green Power LED: Indicates a power normal condition when pulsing. Yellow Battery (Power) Fault LED: Pulses when an off normal condition exists with either the external or internal power source. Red Alarm LED: Pulses when an alarm condition is present. Yellow Detection Fault LED: Pulses when an off normal condition exists in either initiating circuit. The Silence and Reset switches allow silencing of the audible alarms and reset of the control panel respectively. The internal audible alarm is always silenceable, while the audible alarm relay is field selectable for either silenceable or non-silenceable operation. Operation of the reset switch will allow resetting of the control panel after alarm conditions have been cleared. Initiating Circuits The control module contains two supervised detection initiating input circuits that are designed to be connected to contact closure type thermal detectors. The initiating circuits are identical, and detection wiring can be connected to either one or both circuits. An environmentally sealed End-of-Line Module (Part No ) is used to terminate the detection circuit after the last detector in line. If only one detection circuit is used the unused circuit can be terminated inside the enclosure with a 4.7K ohm resistor that is provided with the control module. The initiating circuits are also designed to eliminate nuisance alarms associated with contact bounce in high vibration environments.

15 CHECKFIRE Marine Electric SYSTEM COMPONENTS 2016-JAN-30 REV. 02 PAGE 7 DETECTION CIRCUIT TEST MODULE The Detection Circuit Test Module (Part No ) meets the USCG requirements to provide a simple and convenient means at the control module to individually test each fire detecting circuit by simulating an alarm and trouble condition. The test module is housed in a polycarbonate enclosure that conforms to IEC/EN60947 with protection to IP66. The enclosure contains knockouts on four sides for field wiring. The module contains two 3-position momentary contact selector switches for manually simulating a trouble and an alarm condition in each of the two detection circuits. One switch is designated Alarm Test 1 & 2, and the other switch is designated Trouble Test 1 & 2. See Figure 9. MANUAL FIRE ALARM STATION The non-coded, dual action Manual Fire Alarm Station (Part No ) provides a convenient means to manually initiate a fire alarm. Pulling the handle down causes it to latch in the down position and to close the normally-open switch. The handle is restored manually by unscrewing the allen-head screw so the top of the case can pivot forward, allowing the spring-loaded handle to return to its normal position. The case can then be pivoted back to its normal position and secured with the allen-head screw. The shell, door and handle are molded of red colored LEXAN material (or polycarbonate equivalent) with a textured finish and white lettering. The back plate is 16 gauge steel. Switch contacts are normally open. A weatherproof surface back box (model WP-10) should be used for installation. See Figure in. (80 mm) 4 1/8 IN. (104 mm) TOP 1 3/8 IN. (35 mm) 1 3/8 IN.

FRONT PANEL INDICATORS (See Figure 11) Power Normal (Green) LED pulses once every 3 seconds when indicating normal power The green Power Normal LED pulses on once every 3 seconds indicating power is normal from both sources of input power. If the power drops below an acceptable level from either the internal or external source of input power, the green Power LED will be extinguished. If only one source of power is used, the green Power LED will extinguish when the voltage level drops below an acceptable level. Battery Trouble (Yellow) LED pulses once every 10 seconds when indicating battery trouble The yellow battery trouble LED will pulse when a low power condition is detected in either of the connected supplies (internal or external). If only one power source is used, the control module will automatically ignore the unconnected circuit upon resetting the control module. If a power source is once connected and recognized, a subsequent loss of that power source will be recognized as a Battery Trouble condition. If a power source is once connected, recognized, and then disconnected, the disconnected supply can be ignored by operating the RESET button. Alarm (Red) The Alarm LED will flash if an alarm condition exists. An alarm condition is caused by operation of a detection circuit. The alarm condition will continue until the source of the alarm is removed and the control module is reset.

18 USER INTERFACE PAGE 10 REV JAN-30 CHECKFIRE Marine Electric FRONT PANEL INDICATORS (Continued) DETECTION CIRCUIT ACTIVATION MODE Upon receiving an input signal from a thermal detector, the following functions will be performed automatically: 1. The Alarm LED will flash, the internal sounder will pulse, the alarm relay will transfer resulting in remote alarm operation if connected, and the auxiliary control relay will transfer to operate auxiliary functions if connected. 2. If the silence button is operated during an alarm condition the internal sounder is silenced and, if programmed to do so, the auxiliary alarm relay is also silenced. 3. Operating the Reset button returns the control panel to a fire ready monitoring state providing all alarm and trouble conditions have cleared. Detection Trouble (Yellow) The Yellow Detection Trouble LED and the audio pulse once every 10 seconds when the control module detects a trouble in the detection circuit. The control module will automatically return to normal when the trouble is cleared. Sounder (Audio) The sounder gives a pulsing audio indication for all alarm and trouble outputs. When an alarm condition is initiated, the sounder will pulse at a rate of approximately 2 pulses per second (slow pulse). If the alarm condition is allowed to continue (not removed or reset) for more than 30 seconds, the pulse rate will increase to approximately 4 pulses per second (fast pulse). The sounder gives the audio indications of the various outputs. The sounder is rated at 85 dba at 10 ft (3 m). The pulse rates are as follows: Alarm Slow pulse 2 pulses per second Fast pulse 4 pulses per second Trouble 1 pulse per 10 seconds POWER CONNECTIONS Internal The 3.6 VDC internal lithium battery is connected to the control module by a removable type plug. The battery must be replaced annually. A label is attached near the battery mounting location for recording the installation date.! CAUTION Discharged lithium batteries may contain significant amounts of unused energy and should be handled with care. Do not compact for disposal. Before disposal, each battery must be fully discharged and electrically isolated by enclosing in a plastic bag and sealing the bag. Do not dispose of in fire. Check applicable solid waste disposal regulations for proper disposal of more than one battery. External The external power circuit can be between 12 to 24 VDC. The circuit must be fused at the source on the positive line. The external power source is connected to the module terminal block on terminals No. 1 and No. 2. Both power sources, internal and external, must be utilized. This will always give the fire suppression system a battery back-up when one of the sources are removed for whatever reason. Sounder Yellow Red Yellow Battery Alarm Detection Power Green FIGURE

19 CHECKFIRE Marine Electric USER INTERFACE 2006-SEP-01 REV. 01 PAGE 11 FRONT PANEL BUTTONS (See Figure 12) Silence Pressing the SILENCE button will silence the internal sounder. Pressing the SILENCE button will also silence the alarm relay if the alarm relay has been programmed to silence. The alarm relay silence function is inhibited (locked out) for one minute after an alarm condition is initiated. If an alarm condition is initiated, the operator must wait one minute before silencing. Resetting the panel with an alarm source still present will reinitiate the one minute silence lockout timer. Reset The RESET button is used to re-initialize the control panel. When depressed, it provides an indication that all LEDs and the sounder are functional. It is used to upload the manual programming into the control module. If trouble(s) has not been cleared, the trouble indication will reappear after the RESET button is pressed. When the RESET button is pressed, three short audio and visual indications will acknowledge the switch has been depressed properly. BATTERY REPLACEMENT While in use, the battery requires replacement every year. The shelf life of the battery is 8 years. Control Module contains a label for recording battery replacement date.

21 CHECKFIRE Marine Electric SYSTEM PLANNING 2006-SEP-01 REV. 01 PAGE 13 HAZARD IDENTIFICATION Before the CHECKFIRE Marine Electric Detection and Control System is installed, the hazards to be protected must be identified. These hazard locations determine where the detection wire or thermal detectors and the fire suppression system nozzles are required. While the agent nozzles in existing fire suppression systems will point out the hazard areas, the following information should still be reviewed to best determine detection requirements. If an entire fire suppression/ detection system is to be installed, this information is vital in determining proper placement of discharge nozzles and detection devices. Fire Hazard Definition A fire hazard is any area where an ignition source (high temperature or sparks) and fuel (flammable materials) may be found in close proximity. Examples of ignition sources are engines, exhaust piping, turbochargers, battery compartments, electrical system equipment, torque converters, transmissions, hydraulic pumps, and friction from debris packed around parts. Occasionally other components may reach high temperatures due to malfunction. The potential danger from these components must also be examined during hazard identification. Temperatures in excess of the thermal detector ratings will cause the detection system to activate thereby actuating the alarm system. The above mentioned heat sources can cause fire when they come in contact with flammable materials such as leaking fuel: either broken fuel lines, slow leaks, broken hydraulic lines, or a ruptured fuel tank. Type of Class A materials are part of the vessel itself such as electric wiring insulation, padding, plastic parts, the packages on the vessel, or debris due to poor maintenance. These materials can contribute to the rapid buildup or spreading of fire. Other Considerations Be aware that the propagation of fire from one area to another may cause a hazard to be larger than originally determined. Liquid fuel may spray, splash, or flow carrying the fire some distance from the starting point. Radiation, sparks, or conduction through metal can carry heat to an area where the danger of fire wouldn t normally exist. Also, consider the fire history of the equipment being protected or of similar equipment. Each hazard that is identified should have both fire suppression system fixed nozzles and thermal detectors. Equipment Shutdown Another factor to examine is equipment shutdown. Provisions should be made to shut down any components that could possibly add to the intensity of the fire (fuel pumps, hydraulic pumps, engine, etc.) or any components that could possibly re-ignite the fire once it has been suppressed (battery, electrical system). Although a properly installed fire suppression/detection system is the primary means of protecting equipment from fire, an effective fire protection package also includes provisions for equipment shutdown. The CHECKFIRE Marine control module contains 3 amp 30VDC auxiliary control relay contacts to facilitate connection of shutdown devices. Alarm Application Some areas on a vessel tend to be very noisy. In such cases, a high decibel alarm or bell is available to signal that the control module has received a detection signal. PRE-INSTALLATION GUIDELINES Before actually installing the CHECKFIRE Marine Electric, review all of the following information and plan (sketch) the system layout. This will help to avoid any unforeseen installation problems. Once an acceptable layout has been determined, record and keep it for future reference. Control Module and Actuator Location 1. The control system can be surface mounted. The preferable location is in a clean, dry area with minimum shock and vibration. The control system should be completely visible and accessible for maintenance. Avoid confined areas such as storage closets. If the panel is installed in such an area, personnel will not be aware of a trouble condition, should one develop. 2. The location must be suitable for bolting or welding if bolting is impractical. The mounting surface must be flat to avoid strain on the mounting bracket. 3. There must be room enough to allow for proper wiring connection to the control module. Also, the module should be accessible for periodic inspection and maintenance. The components should be mounted in a location that will not interfere with normal equipment maintenance. NOTICE The ambient temperature in the mounting environment must not fall below 40 F ( 40 C) nor exceed 140 F (60 C). General Wiring The installation of wiring and equipment shall be in accordance with Article 760, Fire Protective Systems, of the National Electric Code (NFPA 70) and with Subchapter J of Title 46 of the Code of Federal Regulations (46 CFR ). Wiring must be marine wiring in accordance with 46 CFR 111. Unless otherwise specified by the authority having jurisdiction, local codes, or on the wiring diagrams supplied for the specific installation, No. 18 AWG, color coded wire is recommended for the detector circuits. Use No. 16 AWG wire for the alarm signaling circuits. Use No. 14 AWG wire for power circuits. All wiring should be multi-conductor jacketed cable with an outer jacket OD of.13 to.25 in. to maintain the watertight integrity of the strain relief at the control module.

22 SYSTEM PLANNING PAGE 14 REV SEP-01 CHECKFIRE Marine Electric Pre-Installation Guidelines (Continued) Thermal Detector Selection Placement Thermal detectors are selected by temperature range relative to the hazard temperature. The table below indicates the thermal detector rated operating temperature and part number. Operating Temperature Detector F ( C) Part No. 140 (60) (71) (88) (107) The placement and selection of thermal detectors should be based on the following requirements: 1. For overheads up to 15 ft (4.6 m), a spacing of 15 ft (4.6 m) between detectors is utilized. 2. Locations with overhead heights greater than 15 ft (4.6 m) require reduced spacing. Contact ANSUL Applications Engineering for assistance in locating detectors in high overhead applications. 3. A minimum setting of 100 F (37.7 C) above ambient temperature is recommended. Detection Circuit Test Switch Module Mount module in a location adjacent to control module which is not subject to damage.

Clean the mounting bracket and mounting surface using a wire brush until clean steel surfaces are available for welding. 3. Secure the bracket to the mounting surface using 1/8 in. (3 mm) fillet welds at the top, bottom, and both sides. See Figure Remove all weld spatter from the bracket and mounting surface. 5. Prime and paint the exposed bare metal of the bracket and mounting surface. Weld 3 IN. (76 mm) Figure If mounting the control module to the bracket, complete the following: With the bracket securely mounted, position the holes in the control module mounting flanges over the holes on the bracket. Using the supplied mounting hardware, securely fasten the control module to the bracket with four flat washers, lockwashers and screws. Remove the cover from the control module. If the internal 3.6 VDC battery is in place, disconnect the wire plug until the field wiring is complete. If the strain relief(s) and plug(s) are not in place, coat the male threads with Dow Corning 737 RTV Sealant or equal and install in holes of module back box. At this point, the external field wiring can be installed. AUDIBLE ALARM INSTALLATION A high pitch audible sounding device is an integral part of the control module for the CHECKFIRE Marine detection and control system.

28 INSTALLATION PAGE 20 REV DEC-01 CHECKFIRE Marine Electric FUNCTION TEST The following tests will verify that the system will operate upon receiving an electrical signal from a detection device (simulated fire condition). If the system is connected to available equipment the test should verify that the auxiliary device functions properly. If noted results are not attained, refer to the Troubleshooting Section of this manual for corrective action. Use Extender Test Cable, Part No , and battery extender cable, Part No , to conduct functional test. The Extender Test Cables allow separation of the cover from the enclosure while maintaining circuit integrity. See Figure 32. Extender BATTERY Cable Extender Test Cable Figure Detection Circuit Functional Test 1. Using a short length of insulated wire stripped at both ends, hold one end of the wire to Terminal 3 and hold the other end to Terminal 4. See Figure 33. Detection Circuit NO. 1 Terminals 3 and Jumper The following will take place while the jumper wire is being held on the terminals: The RED Alarm LED and sounder will pulse at a rate of two times per second for 30 seconds, then increase to four times per second The alarm relay will activate (non-latching) After verifying the above, remove the jumper wire and reset the module. The controller should return to Normal. Normal is when only the GREEN Power LED is pulsing and no other LEDs or the Audio Alarm are operating. Also, the alarm relay will return to normal. Repeat this test for detection circuit 2 by jumpering terminals 5 and If the unit has been programmed to silence the Alarm Relay, repeat test 1 for detection circuit 1 and 2 and test silence function for Alarm Relay. A silence lockout timer will prevent silencing the Alarm Relay for one minute after initiating an alarm. 3. Repeat test 1 for detection circuits 1 and 2 to test Auxiliary Control Relay function. The Auxiliary Control Relay is non-silenceable. PLACING THE SYSTEM INTO SERVICE After all testing has been successfully completed, the system may be placed in service. To place in service, press the reset button. The controller should return to a Normal condition with no alarms or troubles present and the only LED pulsing will be the green LED. Otherwise consult Troubleshooting Section. Detection Circuit Wiring Figure

29 CHECKFIRE Marine Electric INSPECTION AND MAINTENANCE 1998-SEP-01 REV. 0 PAGE 21 To ensure the CHECKFIRE Marine Electric Detection and Actuation System will operate as intended, proper inspection and maintenance procedures must be performed at the specified intervals. DAILY INSPECTIONS The vessel operator must check the system daily by visually verifying that the GREEN power LED is flashing and no other LED is illuminated. Also, no audio alarm should be sounding. If any other conditions exist, contact the local authorized Ansul distributor or whoever has been trained and authorized by Ansul to perform inspection and maintenance checks. DETECTION CIRCUIT TEST The detection circuitry of the control unit can be tested on a daily basis by operating the Detection Circuit Test Module. Prior to testing, all shipboard personnel should be given notice that a test is to take place. The Detection Circuit Test Module tests only the functional integrity of the control module. Periodic tests of the detectors are also required in accordance with the U.S. Coast Guard, National, State, and Local codes and/or the Authority Having Jurisdiction.! CAUTION Operation of the Test Module will simulate an alarm condition. The control relays will operate as if in a real alarm condition and any equipment connected to the Auxiliary Control Relay or Alarm Relay will be affected as it would in an actual alarm condition. Measures should be taken to ensure that this does not affect the safety of the vessel or the personnel on board. To conduct an alarm test for detection circuit No. 1 move the Alarm Test lever to the left, then release lever once the alarms have sounded. Reset the control panel when satisfactory operation of the system has been confirmed. To test detection circuit No. 2 repeat the test by moving the Alarm Test lever to the right. Reset the control panel after successful operation of the system has been confirmed. To conduct a detection circuit trouble test on detection circuit No. 1 move the Trouble Test lever to the left, then release lever after confirming that a detection trouble appears on the control module. Once the lever is released, the control unit should return to normal. Repeat the test for detection circuit No. 2 by moving the lever to the right. MAINTENANCE To give maximum assurance that the system will operate as intended, maintenance must be performed at six-month intervals or sooner depending on the operating environment or maintenance schedule. Maintenance should be performed by an authorized Ansul distributor or whoever has been trained and authorized by Ansul to perform maintenance checks. Visually check components and wiring for wear and damage. DETECTION CIRCUIT CHECK Each detector should be activated one at a time to ensure proper operation. The alarm LED should be checked to ensure proper operation. The control system must be reset after each detector is operated.
